(01. 154-4) ma prior Patent No.1,731,591, granted octo- Berle, 1929, I- described artificial furs,especially imitation astrakhan, obtained by affixing "gibboiisedchenille on a packing made of tissue,- fabric or other suitablematerial.

Chenille is a product consisting of a coie mad of any textile material,cotton for instance, around which are crosswise-'arrangedfibers, alsomade of any textue material, (silk, wool, etc.)

Gibbousingf is an operation that consists in laying circularly the crossfibers of the chenille around their core by passing them throughsuitably heated revolving tubes.-

:"Tne object of this invention is toconstructa machine for making fursimitating naturalastrakhan, according to the process described in myprior application No. 357,089, filed'April 22, 1929, Patent No.1,950,416, granted March 13,1934, of which the present case is adivision; such rocess consisting essentially in previously cutting upsuitably gibboused chenille or'like'material into bits of any desiredshape and size, and in applying such bits on a backing made of fabric,-hide orother materialcoated with a sticky "coating such as, forinstance, rubber cement, so that the saidchenille bits'may be positionedin any order and according to any arrangement whichmey be preferred,permittingan efieot to be obtained which as nearly as possible resemblesthe natural fur. The chenille employed may have been subjected to moreor less marked gibbousing.- Preferably ln order to-obtain a finalproduct offering closer resemblance to astrakhan, and, particularly toincrease its strength, I start with a chenillle having a section orwidth 'of 21 m m-.;or more, previous to gibbousing, which sectlonI-reduce-by gibbousing, to '7 m. m., a ratio given mainly as an indicationand variable according to the amount of curling imparted to the fibersby winding them more or less tightly around their core. When suchwinding extends beyond a complete circle formed by the fibers aroundtheir core, considerable advantage ensures overincomplete gibhousing. g

In the accompanying drawingsi Figurel isa general side elevation of amachine for carrying out'the invention;

Fig. 2 is an enlarged detail view of the chenillecutting mechanism;

Fig. 3 is also an enlarged detail view, showing the driving andconveying device for the chenille bits, and their crowding anddistribution, previous to final application, on a backing;

Fig. 4 is a detail view illustrating the gumming device and the devicefor retouching the chenille bits on their backing before the'latter iswound.

A machine constructed in accordance with my invention comprisesessentially a frame I, one of the ends of which carries the mechanismfor cutting the chenille. Said mechanism is fitted with a conveyorband 2runningover a lower roll 3 and over two rolls 4 and 5. At there isprovided 2.

cylinder permitting the chenille to pass between band 2 and aglass plate1 which will be hereinafter described. v i

Said conveyor band 2 is driven by one of the rolls 3, 4; or which isrotated by any suitable transmission means. Above and at each side ofband 2 are positioned adjustably spaced plates 6 on'which rests theglass plate 1 held, for instance by a cross-strap 8.

Said conveyor band 2 is combined with a second conveyor-band 9 thatpasses over rolls I0 and II carried by frame I. This band 9 is covered,for a distance a-b, by the glass plate 'I and, together with said plate,by a heating surface .|2, held by another cross-strap I3, Said band 9 isdriven, for instance, by means of a pulley M, at a speed lower than thetraveling speed of band 2.

In front of the second band 9 therelis located 1 a circular blade I5rotatedby a suitable motor (not shown), which blade is designed to ,slitthe chenille asWillbe hereinafter-explained. Below said blade is locateda chute 16 leading to a revolving drum ll, the wall l8 of which isperforated. In front ofthe abovedescribed system extends anotherconveyor band 19 running over two rollers 20 and 2 I, and kept underproper tension by means of a' suitabledeviceZZ. Motion is imparted tothis band I9 by roller 20' itself driven by-a belt transmission 23. Onthe side opposite the driving roller EOthereis provided, above band 19,a pressure roller 24 the ends of whichfreely rest in suitable bearings25 (Fig ure 3) carried'by frame I. Band l9, like the conveyorbands ofthe cutting mechanism, is covered along its sides by guiding members 6.Immedi+ ately in front of roller 24 there is arrangedand heldby a. clampor cross-strap 26 a plate 1. made of glassor of any other transparentmaterial. Said plate 1' also covers along the whole width thereof,another conveyor band 28 which runs over a roller 21 parallel withroller 2| and somewhat spaced therefrom. Said band 28 is provided, likethe foregoing one, with guiding members 6 and it runs over a secondroller 29 and over a tensioning roller 30 (Figure 1). Rollers 2| and 21are mounted on supports 3| and wherever convenient on the machine. It isguided by a series of rollers 35, then 'passes through a suitable gluingdevice 36 and next runs over a roll 31 whence it passes toroll 38. Fromroll 38 it goes over'another roll 39, the periphery of which isprovided. with paddles.

Next, it passes through a suitably 'deSig'ned'de vice the duty of whichis to fill up with any powderized textile the gaps between the stuck-0ninbefore explained.

chenille bits. Said powdering device, housed within a casing 40, iscomposed of a drum 4! containing the aforesaidpowder and having aperforated wall (not shown). Said drum is revolved by a suitabletransmission 42 driven by pulley 43. On issuing from casing), backing 34goes to a suitable winding device 45 revolved by a belt transmission 45from pulley '43. J It should be-noted that where it passes-throughcasing 46 the backing 34 furnished with chenille is subjected first tothe action of a beater 46 which assists discharge of the powder'on' thesticky fabric ground between the chenille bits. Said backing next passesover another beater 41 intended to rid it of the excess powderwhich itmay have received. -It should also be noted that,'p'revious toentering'the powdering chamber 49, said backing followsan inclined pathwhich is clearly seen in Figures 1 and 4,-and wherealong may beretouched by hand, if required, the arrangementof the chenille bits onthe sticky surface which has not as yet become dry. A suction funnel 48is provided so as to lead out the objectionablefumes from the rubber'cecompressed. It then comes into contact with the second conveyor band9 which is moving along at a speed slower than the travelling speed ofband 2. Due to. this slowing down, the chenille forms a succession ofbends or loops,

.and while in that condition it is carried along by the second conveyorband 9 under the heating surface l2, the heat from which acts on itafter it has left the cutting-up mechanism. It

' then comesinto contact with blade I51which cuts it up, the bitsfalling intochute l6 and thence into drum l1, l8. Said drum deposits thebits, rid of their impurities, on conveyor band l9, on which they canthen be properly 'distributed either by hand or mechanically overthewhole surface of conveyor band l9, care being taken bits are crowdedtowards end l9 of band 19. Said bits, so crowded, come into contact withband 28;.whereon they are automatically distributed in the propermanner. At 28' they meet the backing 34 which has been coated with glueat 36 and adhere thereto. Said backing, so

treated, next travels along'the above described path to reach thepowdering chamber and nextthe ,winding device 45. Retouching of thechenille bits iseffected on the sloping portion previous to enteringinto chamber 40, as here- It'shouldbe noted that backing'34 and-band 28oughtnotbe driven at the same speed. .SaId drive is obtained bymeans ofapinion 43' se-, cured to the end of cylinder 29 of band 28 and in meshwith another. pinion 431', secured to 'I'wish it to'be clearlyvunderstood that the abovedescribed embodiment is in no, way ,limitativeand that any constructional modifications and changes may be introducedwithout depart-,
